A person on a sled starts descending from the highest point of a snowy slope with a 30º inclination and 150 m in length. The combined mass of the person and the sled is 90 kg. At the end of the slope, they continue moving on a horizontal track until they stop. The coefficient of friction between the sled and the snow is \( \mu = 0.18 \) in both cases. 1. Draw the forces acting on the sled in each section. 2. Calculate the mechanical energy dissipated due to friction on the inclined section. 3. With what speed does it reach the end of the slope? 4. What distance does the sled travel on the horizontal plane before stopping?
